INDOOR UNIT INSTALLATION

PRIOR TO INSTALLATIONBefore installing the indoor unit, refer to thelabel on the product box to make sure that themodel number of the indoor unit matches themodel number of the outdoor unit.

STEP 1: SELECT INSTALLATION LOCATIONBefore installing the indoor unit, you must choose an appropriate location. The following are standards that will help you choose an appropriate location for the unit.

PROPER INSTALLATION LOCATIONS MEET THE FOLLOWING STANDARDS:• Good air circulation.• Convenient drainage.• Noise from the unit will not disturb other people.• Firm and solid—the location will not vibrate.• Strong enough to support the weight of the unit.• A location at least 1m/40" from all other electrical devices (e.g., TV, radio, computer).

DO NOT INSTALL UNIT IN THE FOLLOWING LOCATIONS:• Near any source of heat, steam, or combustible gas.• Near flammable items such as curtains or clothing.• Near any obstacle that might block air circulation.• Near the doorway.• In a location subject to direct sunlight.

INSTALLATION INSTRUCTIONS – INDOOR UNIT

NOTE: ABOUT WALL HOLEIf there is no fixed refrigerant piping, while choosing a location, be aware that youshould leave ample room for a wall hole (see Drill wall hole for connective piping step) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit). However, the unit can accommodate piping to both the left and right.

STEP 2: ATTACH MOUNTING PLATE TO WALLThe mounting plate is the device on which youwill mount the indoor unit.• Remove the screw that attaches the mounting plate to the back of the indoor unit.• Place the mounting plate against the wall in a location that meets the standards in the Select Installation Location step. (See Mounting Plate Dimensions for detailed information on mounting plate sizes.)• Drill holes for mounting screws in places that: a) Have studs and can support the weight of the unit. b) Correspond to screw holes in the mounting plate.• Secure the mounting plate to the wall with the screws provided.• Make sure unit is level.

STEP 3: DRILL WALL HOLE FOR CONNECTIVE PIPINGYou must drill a hole in the wall for refrigerantpiping, the drainage pipe, and the signal cablethat will connect the indoor and outdoor units.• Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions on the next page to help you determine the optimal position. The wall hole should have a 65mm/2.5" diameter at least, and at a slightly lower angle to facilitate drainage.• Using a 65-mm/2.5" core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 5mm-7mm/0.2-0.275". This will ensure proper water drainage. (See FIG. 3.2)• Place the protective wall cuff in the hole. This

protects the edges of the hole and will help seal it when you finish the installation process.

When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

MOUNTING PLATE DIMENSIONSDifferent models have different mounting plates. In order to ensure that you have ample room to mount the indoor unit, the diagrams to the right show different types of mounting plates along with the following dimensions:• Width of mounting plate.• Height of mounting plate.• Width of indoor unit relative to plate.• Height of indoor unit relative to plate.• Recommended position of wall hole (both to the left and right of mounting plate).• Relative distances between screw holes.

REFER TO THE FOLLOWING DIAGRAM TO ENSURE PROPER DISTANCE FROM WALLS AND CEILING:

CAUTION

FIG. 3.1

STEP 4: PREPARE REFRIGERANT PIPINGThe refrigerant piping is inside an insulatingsleeve attached to the back of the unit. You mustprepare the piping before passing it through thehole in the wall. Refer to the Refrigerant PipingConnection section of this manual for detailedinstructions on pipe flaring and flare torquerequirements, technique, etc.• Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit.• If the wall hole is behind the unit, keep the knock-out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. (See FIG. 3.3). This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand.

BE EXTREMELY CAREFUL NOT TO DENT OR DAMAGE THE PIPING WHILE BENDING THEM AWAY FROM THE UNIT. ANY DENTS IN THE PIPING WILL AFFECT THE UNIT’S PERFORMANCE.

• Use scissors to cut down the length of the insulating sleeve to reveal about 15cm/6" of the refrigerant piping. This serves two purposes: a) To facilitate the Refrigerant Piping Connection process. b) To facilitate gas leak checks and enable you to check for dents.• If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose step. If there is no embedded piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions.• Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of your piping.• Grip the refrigerant piping at the base of the bend.• Slowly, with even pressure, bend the piping towards the hole. DO NOT dent or damage the piping during the process.

NOTE: ON PIPING ANGLERefrigerant piping can exit the indoor unit from four different angles:• Left-hand side• Left rear• Right-hand side• Right rearRefer to FIG. 3.4 for details.

REFRIGERANT PIPING CONNECTION

CONNECTION INSTRUCTIONS –REFRIGERANT PIPING

STEP 1: CUT PIPESWhen preparing refrigerant pipes, take extra careto cut and flare them properly. This will ensureefficient operation and minimize the need forfuture maintenance.• Measure the distance between the indoor and outdoor units.• Using a pipe cutter, cut the pipe a little longer than the measured distance.• Make sure that the pipe is cut at a perfect 90° angle. Refer to FIG. 5.1 for bad cut examples.

NOTE ON PIPE LENGTHThe length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominalefficiency is tested on units with a pipe length of 5m/16.5'. Refer to the table below for specifications on the maximum length and drop height of piping.

MAXIMUM LENGTH AND DROP HEIGHT OF REFRIGERANT PIPING PER UNIT MODEL

DO NOT DEFORM PIPE WHILE CUTTINGBe extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit.

STEP 2: REMOVE BURRSBurrs can affect the air-tight seal of refrigerantpiping connection. They must be completely removed.• Hold the pipe at a downward angle to prevent burrs from falling into the pipe.• Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

STEP 3: FLARE PIPE ENDSProper flaring is essential to achieve an airtight seal.• After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from entering the pipe.• Sheath the pipe with insulating material.• Place flare nuts on both ends of pipe. Make sure they are facing in the right direction, because you can’t put them on or change their direction after flaring. See FIG. 5.3.

• Remove PVC tape from ends of pipe when ready to perform flaring work.• Clamp flare form on the end of the pipe. The end of the pipe must extend beyond the edge of the flare form in accordance with the dimensions shown in the table below.

PIPING EXTENSION BEYOND FLARE FORM

• Place flaring tool onto the form.• Turn the handle of the flaring tool clockwise until the pipe is fully flared.• Remove the flaring tool and flare form, then inspect the end of the pipe for cracks and even flaring.

STEP 4: CONNECT PIPESWhen connecting refrigerant pipes, be carefulnot to use excessive torque or to deform thepiping in any way. You should first connect thelow-pressure pipe, then the high-pressure pipe.

MINIMUM BEND RADIUSWhen bending connective refrigerant piping, the minimum bending radius is 10cm/4"(See FIG. 5.6).

INSTRUCTIONS FOR CONNECTING PIPING TO INDOOR UNIT• Align the center of the two pipes that you will connect (See FIG. 5.7).

• Tighten the flare nut as tightly as possible by hand.• Using a spanner, grip the nut on the unit tubing.• While firmly gripping the nut on the unit tubing, use a torque wrench to tighten the flare nut according to the torque values in the Torque Requirements table (next page). Loosen the flaring nut slightly, then tighten again.

EVACUATION INSTRUCTIONSBefore using the manifold gauge and vacuum pump, read their operation manuals to familiarize yourself with how to use them properly.

• Connect the charge hose of the manifold gauge to service port on the outdoor unit’s low pressure valve.• Connect another charge hose from the manifold gauge to the vacuum pump.• Open the low pressure side of the manifold gauge. Keep the high pressure side closed.• Turn on the vacuum pump to evacuate the system.• Run the vacuum for at least 15 minutes, or until the compound meter reads -76cmHG (-10 Pa).• Close the low pressure side of the manifold gauge, and turn off the vacuum pump.• Wait for 5 minutes, then check that there has been no change in system pressure.• If there is a change in system pressure, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system pressure, unscrew the cap from the packed valve (high pressure valve).

FIG. 6.1

FIG. 6.2

• Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench in a .25" counterclockwise turn. Listen for gas to exit the system, then close the valve after 5 seconds. • Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The Pressure Gauge should read slightly higher than atmospheric pressure.

• Remove the charge hose from the service port.• Using hexagonal wrench, fully open both the high pressure and low pressure valves.• Tighten valve caps on all three valves (service port, high pressure, low pressure) by hand. You may tighten it further using a torque wrench if needed.

OPEN VALVE STEMS GENTLYWhen opening valve stems, turn the hexagonal wrench until it hits against the stopper. DO NOT try to force the valve to open further.

A/C – Air conditioning also referred to as A/C. A system or device for reducing the temperature and humidity, in a space.

AHAM – Acronym for Association of Home Appliance Manufacturers. AHAM produces the official rating for dehumidifiers.

BTU – British Thermal Unit. A single BTU is the amount of energy required to cool or heat a pound of water one degree Fahrenheit.

Condenser – The unit used to condense a substance from a gaseous state to liquid by cooling it. Condensers are generally recognized as heat exchangers. In the case of air conditioners they extract the inside heat from the interior of the air conditioner to the outside air. Often referred to as “the outdoor unit.”

Dehumidifier – Also called, dehums. Dehumidifiers remove humidity and are used to keep a rooms humidity levels in check. Maintaining correct humidity will ensure a healthy crop. Too much humidity will cause molds, rot and devastate your crop.

Digital Inverter Compressor – A digitally controlled compressor that converts AC voltage to DC voltage to control compressor speed. The inverter allows precise throttle control of the conditioning unit based on the load or need. Inverter units are quieter, more efficient and last longer.

Ductless Mini-Split – An air conditioner or heat pump that requires no duct work to function. The unit hangs on the wall or ceiling and cools or heats the surrounding area.

Evaporator – The indoor portion of the heat pump or air conditioner. In a mini-split system this hangs on the wall or ceiling and provides the heating or cooling of the space.

H/P – Heat Pump. A unit that can operate as both an air conditioner or a heater. When it’s cold outside a heat pump extracts the outside heat and transfers it inside. When it’s warm outside, it reverses directions and acts like an air conditioner, removing heat. A heat pump moves heat instead of generating it, giving you more energy efficiency.

HSPF – Heating Seasonal Performance Factor. The greater the number/rating the more efficient the heating. A 10 HSPF, for example is a very good rating.

Humidifier – Humidifiers use water to put humidity in the growing space. Many plants we grow indoors are accustomed to growing outdoors in tropical areas where humidity is high. Also certain parts of the country are drier than others so you will need to add humidity.

Line Set – Insulated copper tubing used to connect the evaporator and condenser. The refrigerant travels back and forth through the line set between the evaporator and condenser to create either cooling or heating.

R-410 – A type of refrigerant. Unlike alkyl halide refrigerants, R-410A (which contains only fluorine) does not contribute to ozone depletion. Because of that attribute it’s preferred and used more broadly instead of R-22 which are phased out. R-410 refrigerants allow for higher SEER ratings therein reducing power consumption and improving unit efficiency.

SEER – Seasonal Energy Efficiency Ratio. The greater the SEER rating, the more efficient the cooling system. The minimum SEER rating allowed by the Federal Government is 14.

Ton – The size of air conditioning unit (heating or cooling) is common referred to in “tons”. A one ton unit, for example, is 12,000 BTU’s. A two ton, 24,000 BTU’s, etc. This was arrived at using a standard of how long it would take to melt ice. A one ton unit takes 12,000BTU’s of heat one hour to melt a ton of ice.

VFD – Variable Frequency Drive. The VFD is a an electrical device that’s used to control the speed and torque of an air conditioning motor, like those used in an inverter compressor.
